Cyber security consultants perform many of the same functions as cyber security engineers, but they are hired (either as agencies or individuals) to work for clients. Often this means that they’re evaluating systems for vulnerabilities, setting up a new and functional system, and then leaving the client to maintain the system with internal personnel.
Cyber security consultants represent a unique skill set in the industry. Because they are hired from outside of the organization in need, they have to have equally high standards in their ability to work with diverse companies, understanding and communicating with those they often don’t have long-term relationships with, and in their wide but deep technical expertise, which allows them to recognize problems efficiently and in different settings. Unlike other roles in the cyber security industry, consultants are constantly proving their worth (just as a freelancer would).
